内容記述 Theories of the laminar boundary layers on spinning bodies of revolution and experiments on the turbulent boundary layers on various rotating bodies in axial flows with or without pressure gradients are presented. The laminar boundary layer theories concern with a rotating body of arbitrary shape in a uniform stream or in a quiescent fluid and with rotating thin cylinder in a uniform stream. For the first flow problem a universal series solution is obtained and also a universal series solution is calculated for the thermal boundary layer of the second problem. A higher order consideration is developed for the third flow. The acceleration phenomenon in the boundary layer induced by the rotation of a thin cylinder is clarified by use of a perturbation method. The thick turbulent boundary layers on rotating cylinders with a ring or a step in a constant pressure flow are examined. The roughness element disturbs the velocity distribution in the turbulent boundary layer, especially in the meridional direction strongly. The velocity profile in the azimuthal direction is rather stable to such a disturbance. An expression of generalized quasi-collateral condition of the velocity distribution is obtained. The effect of pressure gradients on the turbulent boundary layer on a rotating cylinder is clarified in the final chapter. The imposed pressure gradients are adverse and favorable. The shear stress distribution in the peripheral direction is calculated and the existence of the constant moment layer is shown. A universal logarithmic velocity distribution law in the peripheral direction is established by use of a matching method. A role of a Richardson number as a representative of a character of this flow is discussed.
